Malleable Iron Axle Skeins.

I'MPROVEMENT IN MALLEABLE-IRON AXLE-SKEINS.

Specification formin g part of Letters Patent No. l34,l89, dated December 24, 1872.

GASE B.

To all whom it may concern:

Be it known that I; ANDREW J. ALSTON, of the city and county of Allegheny, and State of Pennsylvania, have invented a certain new and useful article of manufacture-an AXle-Skein coustructed of CaSt-Iron, subsequently converted into Malleable Iron, and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the'accompanying drawing and to the letters of reference marked thereon.

The nature of my invention consists in furnishing anew article of manufacture, viz: An axle-skein constructed of castiron, subscquently converted into aalleable iron. 4

To enable others skilled in the art to make my new article of manufacture, I will proceed to describe more fully its Construction.

In the accompanying drawing, which forms part of my specification, Figure l is a side view of my improved aXle-skein and its pipebox. Fig. 2 is a longitudinal section of the same; and Fig. 3 is a transversesecton of the same at line w of Fig. 1.

In the aecompanyin g drawing, A represents the`axle skein, which is provided with braces' B for the collar G, which may form part of the skein A, or may-be made separate from it, but, in either case, the skein should be pro vided with the braces B. The sken is provided with an opening, D, through it for the reception of the axle. f represents the pipebox for the hub of the wagon-wheel. g represents the Washer, and h the linch -pin. The skein Ais provided with an opening for the bolt (indicated by dotted lines at i) used for securing it on the axle, and is also provided with openings for the 1inch-pin.

The skein A, collar 0, pipe-box f, Washer g, and linch-pin h, are constructed of cast-iron, through the medium of suitable patterns, and by the molding and casting process well understood by iron molders and foundrymen. The castings are made of 'that brand of pgiron known among foundrymen as Missouri White Pig, or other pig-iron of the same nature, and having the same properties. i

The'several parts, after being cast, are properly cleaned, after which the skeins, collars, washers, and linch-pins are packed in an annealing-compcund and placed in an annealingoven and subjected to heat until the castings are converted into malleable iron, which process of converting is well understood by manufacturers of malleable castings.

An aXle-skein constructed as hereinbefore described will be very strong and cheap, and can be made with great facility, saving labor and time in its production; and, in use, it will be found that the pipe-box will turn upon it with less' friction than upon the ordinary wrought or cast iron skeins.

What I claim as of my invention is-- A new article of manufacture-an aXleskein made of malleable iron, substantially as herein described, and for the purpose set forth.

ANDREW J. ALSTON.
